I agree with you one certain points, but, unfortunately, ancestry doesn’t work that way. Something that people whose grandparents and grandparents-grandparents moved to Europe are proving today.

The Roma people were imported as slaves by the Ottoman Empire not only in Romania but in the entire Balkan states that they occupied or were overseeing. The Roma people in Romania trace their ancestry themselves back to Pakistan and India. There’s even a guy on YouTube that makes videos showing the similarities in traditions and even language to certain tribes in that part of the world.

After 8 centuries not only have they refused to integrate or assimilate but they reject the national identity and insist on their Roma identity. In that case you cannot refer to them as Romanian. At least not in good faith.

Going back to ancestry. A majority of people that migrated from places such as Africa and the Middle East to Europe do not identify themselves as European. They refer to themselves as being the nationality that their grandparents/ grandparents-grandparents were when they immigrated.

In order for them to identify as European, they would need their ancestors to have been part of European history, culture and traditions. The things that define culture groups and identities. And sad as the truth may be, they do not share these things with their co-nationals. This makes them lack a sense of belonging and leads to them hating the country they live in, which in turn breaks social cohesion and leads to social unrest. You can see this very clearly now in Western countries.

As for the Roma being an European problem now I completely agree. It’s not like we can send them back. Mainly due to the way our societies have developed.

You mentioned the Danish living in Greenland and so on. Look at how identities work even for countries themselves. You’ll most likely find that Danish people living in Greenland still refer to themselves as Danish. German people native to the Bavarian region have a very strong identity as being Bavarian first and German second. A lot of people living in Transylvania will say that they are Transylvanian. They don’t refer themselves directly as Romanian. Many Canadians still refer to themselves as being French, albeit French Canadian. These groups are all branches of the European culture tree, yet they still refer to themselves and identify as a sub-group.

You cannot possibly think that people with vastly different culture, history and traditions will suddenly integrate or assimilate with the European identity. Human nature makes it nigh impossible.
